Spider Farmer's entry-level panel, and probably the best seller in the whole range. A hundred watts for a 2' × 2' square: the size that matches a basement corner, a small tent, or one or two plants carried from seed to harvest.

Two things separate this lamp from generic panels at a comparable price. First the diodes: Samsung LM301H EVO, the most recent generation of Samsung's white series, more efficient than the LM301B it replaces and enriched in the blue-violet region of the spectrum. Then — and this is the point buyers underestimate most — the power supply: a Mean Well. In an LED lamp it's almost never the diodes that fail first, it's the driver. A recognized-brand supply is the difference between a lamp that lasts years and a lamp that dies in its second season.

How to read the coverage: the same lamp always covers a larger surface in vegetative growth than in flowering or fruiting, simply because a plant making leaves needs considerably less light than a plant filling fruit. The 2' × 2' stated here is the surface where the lamp gives its full output. For seedlings, lettuces or herbs, which ask far less, it comfortably lights more.

In our tent range, it's the natural companion to the 90 × 90 cm tent, which is roughly 3' × 3'.
